Is there a way to Idenetify them easily? /forums/images/graemlins/ears.gif
 
Im sure there is a number cast on the axle somewheres so you can check date of manufacture? I mean they were only used from 88-91 AFAIK.
 
Did the number of splines change over the years ? (older vrs. newer)
I am just curious , wouldn't want to buy parts if they are not a direct swap lol. /forums/images/graemlins/doah.gif

They changed in 89 AFIK on Blazers.

(I just double checked the specs page and that is what it says)
